According to the plan of this zone of the river, which has 

 been specially prepared to project the buoying; 25 luminous 

 would be sufficient to mark the navigable channel from 

 the mouth of the river Uruguay to Fray Bentos. 



Generally the sites indicated for the buoys are the promi- 

 nent points of the channel and the places where the banks 

 are the steepest, placing two buoys where the channel is 

 narrow and dangerous. At the beginning and at the end 

 of the projected channel in the «Barrial» pass two buoj r s 

 will be provided. It will be noticed, that according to this 

 project, there will be when going up river 11 buoys carry- 

 ing white or green lights on the portside of the channel, 

 14 carrying red lights on the starboard side. 



In concluding it must be acknowledged that for the 

 exactness of the soundings shown on the plan, the obser- 

 vations made since the year 181)6 at the gauge of the mole 

 of the « Extract of Meat Factory » at Fray Bentos, have 

 been of the greatest utility and that they were most kindly 

 supplied to this Commission by the Manager of said 

 Factory. 

 The Guaieguaychu The first Argentine port when going up river is that of 

 Gualeguaychii : it is situated some 20 kilometers from the 

 mouth of the river of the same name and some 33 kilome- 

 ters from the bay of Fray Bentos (Sheet 6). 



This river has a mean width of 100 meters by a mean 

 depth of 8 feet. It has only one notable curve, but as its 

 radius is 300 meters, it is of no considerable inconvenience 

 to the actual navigation. 



The difficulty which vessels of a regular draught meet 

 consist in two shallow bars of stone: one of them is 

 near the mouth of the river, the other in the neighbourhood 

 of the port. The firsi one has an extension of 200 meters 

 and is covered by only three feet of water when the river 

 is \ cry low. 



Besides those bars there are isolated rocks which are 

 imperfectly known spread over the whole length of the 

 river and which are dangerous to navigation- 



To the difficulties of the mentioned river is to be added 

 the extensive bar existing a1 its mouth, which. Formed by 

 mud, makes navigation impossible when the river is low, 



river.
